Specification of Letters Patent.

Patented Jan. 115, 19118.

Application filed January 22, 1917. Serial Ito. 143,608.

To all whom it mat] concern:

- a full, clear, and exact description.

- My invention relates to metallic frames and has reference more particularly to builtup frames. The object of the invention is to provide a simple, inexpensive, and strongframe structure which can be built up rapidly to any desired size.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views. 1

Figure 1 is a perspective view of a frame embodying my invention;

Fig. 2 is, a vertical cross section on line 2-2, Figure 1:

Fig. 3 is a horizontal cross section on line as, Fig. 1;

Fig. 4 is a cross section through the bottom member of the frame on line l4,

Fig. 5 is a bottom-up perspective view of a lower corner of the frame; and Fig. 6'is a perspective view of a modified structure of a frame of which one corner is shown. In the manufactureof metallic frames of the channeled type it is customary to keep standard sizes of frames made up in stock, and when an order is given for a frame of larger or smaller size than the standard ones the deliverycannot be made until a certain time. that is, the time necessary to make up the frames. In most frames of this type the corner issoldered to thechanneled member and the work requires considerable time.

The object of my invention is to provide tween the channeled members and the cor ners of the. frame. By keeping in stock various lengthsof channeled members, any

size of frame can be quickly built up and deliverymade within 24 hours. Furthermore,

H ber. frame in which there is a driving fit beframes already in stock can be. easily taken apart and remodeled for frames of different sizes at comparatively little expense and labor.

The frame comprises a channeled bottom member 7 which is driven into horizontal arms 8 of corners 9 provided at the ends thereof. These corners 9 are each made from a blank into a channel-shaped corner by a method well known in the art. One of the arms of such a. corner has the bottom of the channel open longitudinally, as shown at 10. The opening is in the arm 8 and, consequently, the arm 8 is'weaker than the arm 11 of the same corner.

The sides of the arms 8 and 11 are folded inwardly, as shown at 12, so as to engage the inner surface of the channeled members. For example, the arms 8 by engaging with their infolding portions 12 the channeled member 7, considerably strengthen said arms, which would otherwise have a tendency to open due to the longitudinal opening 10 in the bottom thereof. The side channel members 13 have also a driving fit into the arms 11 of the corner 9. The upper corners 14: are similar to the corners 9 when the frame has for its upper member a channeled member, but in cases where the frame is to be used for cards, the upper corner members 14 are slightly different.

The arm 15 of each corner is exactly similar to the arm 11 of the corner 9; but the normally longitudinal open arm 16 differs from the arm 8 of the corner 9 in that it has infolded portions not only at the inner edges of the arm but at the outer edges also, as shown at 17. These infolded portions 17 provide the necessary passage for the card into the side channel members 13, and also serve as an additional grip for thecorner with the fiat bars 18 which bind the arms 16 of the upper corners 14. The thickness of the bars 18 is substantiallythat of the thickness of the sides of the channeled members 7 and 13, and their width that of the width of the side of a channeled mem When the frame is to be used with cards, the bottom channeled member 7 is provided with a'bearing 19 for a support. This hearing is in the shape of a channeled member the sides of which are infolded at the longitudinal edges to form a driving fit with the seen that all that is necessary is to keep in stock corners as described and standard lengths of channeled members, and when an order for such frames is received they can be assembled very rapidly. In cases where an odd size of frame is required, special lengths of channeled .members may be cut, the same corners being used in connection therewith. No soldering or riveting is necessary, and the normally weak open arms of the corners are strengthened when they are driven on to the channeled members, as previously explained.

I claim:

1. A frame of the class described comprising channel-shaped corner members having one arm thereof open longitudinally at the bottom, said corners having infolded side portions at the longitudinal edges of the arms, and channel-shaped members hav ing a driving fit with the arms of the corners. and adapted to be engaged with their sides between the sides. and the infolded portion of the corners of the arms, whereby the open arm of the corner is reinforced.

2. A frame of the class described co m prising a channeled bottom member, channeled side members, channeled corners binding the side members to the bottom members, said corners presenting inwardly folded side portions for engaging the sides of the channeled bottom and side members, a pair of flat bars forming the top member of the frame, and corners binding the side members to the bars, said corners having inwardly folded side portions at the inner and outer edges for engaging each bar, substantially as and for the purpose set forth.

3. A frame of the class described comprising a channeled bottom member, channeledside members, channeled corners binding the side members to the bottom members, said corners presenting inwardly-folded side portions for engaging the sides of the channeled bottom and side members so that a driving fit is formed between the corners and'the channeled members, a channelshaped bearing having infolded sides at the longitudinal edges and having a driving fit on the channeled-bottom members, said bearing having means for engaging a standard from which the frame is to be supported, a pair of flat bars forming the top member of the frame, and channel-shaped corners binding the side members to the bars, said corners having inwardly-folded side portions at the inner and outer edges for engaging each bar and presenting an opening to provide entrance for a card to the sidebhanneled members.
